WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
The AAD blade is a spoiler plate which moves up and down in a vertical plane, via linkage to a screw-drive mechanism, which is controlled by two actuator motors. The AAD is typically serviced as an entire assembly, which includes the AAD blade, AAD actuators, mounting brackets, screw-drives, and jumper wiring harness and also AAD actuators and AAD blade can be serviced individually.
